DOOR-LOCK.

Specification of Letters Patent.

Patented Nov. 25, 1913.

Application filed January 27, 1913. Serial No. 744,461.

T 0 all whom it may concern. Y

Be it known that I, GEORGE KIEHL, a citizen of the United States,residing at Somonauk, in the county of Dekalb and State of Illinois,have invented certain new and useful Improvements in Door-Locks, ofwhich the following is a specification, reference being had therein tothe accompanying drawm lhis invention relates to door locks and has forits object the production of a simple and efficient detachable doorsecurer or look which may be attached to a door in such a manner as toprevent the same fromb'e' coming detached therefrom from the outside.

Another object of this invention is the production of a simple andefficient device which is formed from a blank sheet of material and isso constructed as to acommodate itself to doors which have swollen orshrunken under conditions of the atmosphere.

With these and other objects in view, th1s invention consists of certainnovel constructions, combinations and arrangements of parts, as will behereinafter fully described and claimed.

In the drawing :Figure 1 is a longitudinal section through the deviceshowing the same applied to a door fitting somewhat snugly upon thejamb. Fig. 2 is a sectional view similar to Fig. 1 showing the deviceapplied to a door which does not fit closely in engagement with the jamb. Fig. 3 1s a view similar to Fig. 1 showing a door fitting snugly inengagement with the j amb. Fig. 4 is a detail perspective of the doorsecurer.

By referring to the drawings, it will be seen that 1 designates the doorto which the securer is attached for firmly holding the door in a closedposition relative to the jamb 2.

The door securer comprises a primary section 3 and an auxiliary section4. The primary section 3 comprises an elongated spring sheet metal bodywhich has its outer end bent upwardly as indicated at 5, so as toconstitute a knob 6 for engaging the auxiliary section 4. The extremeend of the primary section 3 terminates in a rightangularly extendingdoor engaging point 7 for firmly securing the primary section inengagement with the door. This point 7 tapers toward its outer end so asto facilitate the securing of the primary section in en gagement withthe edge of the door. The primary section 3 is provided with a pluralityof spaced apertures 8 for the purpose of receiving the cotter pin 9which cotter pin is adapted to pass through the aperture 10 formed inthe auxiliary section 4 for anchoring the two sections 3 and 4-together. i

The auxiliary section 4 comprises an elongated body, and, like theprimary section 3, isprovided with an outwardly bent end 11 forconstituting a shoulder to be engaged by the knob 6 of the primarysection when it is so desired to accommodate the device to a differentkind of door. The outer end of the auxiliary section 4 is bent at rightangles to the body to constitute a jamb engaging finger 12 as indicatedin Figs. 1 and 4:, and this jamb engaging finger is adapted to lie flatagainst the jamb to firmly hold the auxiliary section and primarysection in their correct positions. An adjusting band 13 is slidablymounted upon the primary sections 3 and 4 and this adjusting band slidesover the outer ends 14 of the primary and auxiliary sections for firmlyholding the sections against pivotal movement relative to each other.This band will also efliciently reinforce the two sections of thesecurer so as to add additional spring action to the sections by bindingthe outer ends closely inengagement with each other and causing thelower ends to also closely engage each other thereby having the body ofthe primary section bulging outwardly as indicated clearly in Fig. 1.

From the foregoing description, it will be seen that a very simple andeflicient device has been produced whereby the door securer willaccommodate itself to different width spaces between the door and jamb,thereby allowing the device to be attached to doors which have becomeworn as well as doors which have been recently hung. It is a well knownfact that where doors are first put up in new houses, the space betweenthe j amb and the edge of the door is very small and in such a case thedevice is applied to the door and jamb, as indicated in Fig. 3. When,however, the door is old and has been in use for some time the samegenerally shrinks and wears along its edge so as to enlarge the spacebetween the jamb and the door itself. The securer may, therefore, expanditself, owing to its spring action, to the position as indicated inFigs. 1 and 2, thereby accommodating itself to difierent conditionsunder which it has to act.

Having thus described the invention, what is claimed as new, is 2- Adoor securer of the class described comprising a primary and anauxiliary section, a connecting loop positioned upon the outer end ofsaid sections for holding the same together, each section provided witha plurality of spaced apertures, each section comprising a spring body,said primary section provided with an outwardly bent end terminating ina knob and provided with a right angularly extending door grippingpoint, said auxiliary section comprising an outwardly bent endterminating in a right angularly extending jamb engaging lip eX- tendingin an opposite direction to the point of said primary section, saidoutwardly bent portions of said primary and auxiliary sections adaptedto exert an outward pressure upon the body of said sections for causingthe body of said sections to accommodate itself to different widthspaces, said outwardly inclined portions abutting against each other forconstituting a yieldable contact and facilitating the compression of onesection upon the other, and means passing through said apertures in saidprimary and auxiliary sections for securing the same together.

In testimony whereof I hereunto afiix my signature in presence of twoWitnesses.

GEORGE KIEHL.
